Abstract
A magnetic height-height correlation function was used to quantitative ly analyze the magnetic force microscope (MFM) images of the DC-demagn etized state of two thin film media. This function provided important information about the micromagnetic features of these media, including the global magnetic roughness, the local magnetic roughness, the stre ngth of long-range magnetostatic interaction, and the degree of local intergranular exchange coupling. These features are accountable for th e noise performance of these media detected by the recording head.
